CAD of a State Feedback Law Via Shaping Bode Diagram

Abstract This paper considers the problem to design a state feedback law for a linear multivariable system, which is completely determined by specifying poles and eigenvectors of the closed loop system. It is shown what rules the specifications of the desired poles and eigenvectors play in shaping Bode Diagram of the treated system. The robustness criterion is represented as the paticular shape of Bode Diagram of the return difference matrix. Based on the results, the procedure to design the state feedback law which yields the robust closed loop system is discussed.
